WALL CONSTRUCTION.

Specification of Letters Patent.

Patented Mar. 18, 1919.

Application filed June 26, 1916, Serial No. 108,022. Renewed July 29, 1918. Serial No. 247,249.

To all whom it may concern:

Be it known that I, RALPH F. YOURTEE, a citizen of the United States of America, residing at St. -Louis, State of Missouri, have invented new and useful Improvements I- in Wall Construction, of which the followthe structure may be knocked down and transferred from one point to another if de sired.

While the slabs are composed of like material and are of similar general configuration one slab is provided at its opposite ends with interlocking elements, rldges or grooves I which are adapted to engage grooves or ridges-provided at the ends of the adjacent slabs. vertical wall when assembled and the interlocking joint between the adjacent slabs occurs at the corners of the wall. Therefore,

the slabs are provided with additional locking means at their corner portions of the wall which prevent the adjacent sections of the wall from spreading. v

In the accompanying drawings Figure l is a perspective view of a portion of a wall with the slabs disconnected from each other;

' Fig. 2 is a fragmentary sectional view of adjacent slabs locked at a right angle to each other;

Fig. 3 is a similar view with the locked slabs ,disposedat an obtuse angle to each other; i

Fig. 4 is a detailed perspective view of the end portion of one of the slabs;

Fig. 4 is an under plan view of the slab shown in Fig. 4;

Fig. 5 is an under plan view of another of the slabs;

Fig. 6 is a fragmentary vertical sectional view of the connected slabs.

As illustrated in the accompanying drawings, the slabs A are intended to be set or laid upon the ground or a suitable foundation. Each slab A is provided at its opposite ends and at corresponding corners with The slabs constitute sections of a' recesses 1, the said recesses extending a portion of the vertical height of the said slab. Each recess 1 is provided at its inner wall With a vertically disposed ridge 2, the said ridges extending the full vertical length of the inner walls of the said recesses. It is to be understood that if desired the ridges shown and described in connection with the slab A may be replaced with grooves, it being optional whether the ridges or grooves are, applied to the slabs A and corresponding grooves or, ridges applied to the other slabs hereinafter described.

The slab A is provided at its inner side and in the vicinity of its opposite ends with ridges 3 which are located beyond the inner wall of the recesses 1 and which extend from the median line of the slab A to the upper walls of the said'recesses as best shown in Fig. 4 of the drawing. The slab A is provided in the vicinity of its opposite ends with grooves 4 which are vertically alined with the ridges 3. It is to be understood that if the ridges 3 and grooves 4 are employed upon the slab A corresponding grooves and ridges are employed upon the slabs B and O and vice versa.

The slabA is provided at its upper edge with a longitudinally disposed groove 5 which terminates at its ends short of the ends of the said slab. The said slab is further provided at its upper edge and in the vicinity of its ends with cross grooves 6 which lead in at the ends from the grooves 4 and at their other ends terminate short of the outer face of the slab. The slab A is provided at the upper walls of its recesses 1 with cruciform ridges 7. (See Fig. 4

Each slab B is provided at its opposite ends with a recess 8 which extends a portion of the way of the vertical height of the slab B.: As shown in Fig. 1 the slab B is provided at the inner walls of the recesses 8 with grooves 9 adapted to receive theridges 3 of the slab A when the said slabs are assembled. The said slab B is also provided at its inner side and in the vicinity of its opposite ends with grooves 10 which are located beyond the inner walls of the recesses 8 and which are adapted to receive the ridges 2 of the slabs A when the said slabs are assembled. The substitution of ridges for the grooves 9 and 10 may be made when the substitution of grooves for the ridges 2 and 3 upon the slab A is made. When the slabs A and B are assembled and connected with each other they are disposed at angles with relation to each other and the locking joint occurs at the corner portions of the structure. The slab B is provided at the lower walls of its recesses 8 with cruciform grooves 11. The slab B is provided at its upper edge with a longitudinally disposed groove 12 which communicates at its ends With the grooves 10. The cruciform grooves 11 of the slabs B are adapted to receive the cruciform ridges 7 of the slab A when the slabs are assein led. Each slab C is provided at its ends with recesses 13 there being provided at-the inner Walls or" the said recesses ridges l-l. Each slal) (l is provided at its lower edge with a hingitudinalljy' disposed ridge 15 -which communicates at its ends with the ridges 1%. The ridge 15 of the slabs Q Which is positioned above the slab B is received Within the groove 12 of the slab B. The ridge 14: of the lowermost slab C supported upon the slab B is received in the groove 4 of the slab i i. ihe slab C is provided at the upper walls of its recesses 13 with cruciform ridges 16. The ridges 16 of the lowermost slab C supported upon the slab ll are received in the end portions of the grooves 5 and 6 of the lowermost slab A. The slalo G is provided at its same side and in the vicinit} of its opposite ends With grooves 1*? which connnunicate at one end with portions of the cruciform ridges 16 as best shown in Fl 5 of the drawing. The [[1 l? of the slabs C which are supported the slab B are adapted to receive the i l e of the slahs C which are supported 1 the slab i when the slabs are as n The slabs are provided at th edges with longitudinally disposed grc 18 which at their ends terminate short of ends or the said slab. "ihe said slob C is turther provided at its upper edge with grooves 19 which communicate at one end with the grooves 1. and at their other ends terminate short of the outer -face of the slab U. lhe grooves 19 are disposed transvers the grooves 18 as best shown in Fig drawing. li' hen the slabs C are one upon another the groove 1 slaih receives the ridge 1' above and the groove o" is supported upon the the rid e 15 of a slab U which rpportec. upon th slab A liroin the foregoing description taken in conjunction with the accompanying orawing it will he understood that when the slabs are assembled they form a strong and durable structure and that they interlock with each other Without the necessity of inert or plastic cement, consequently they may no readily taken apart and the structure may he transferred from one point to ano Also the structure is provided with st ong and duralhle interlocking corner joints Where 3; the structure may sustain conside 'alhle Weight Without danger of the slabs n spreading or becoming disarranged in consequence of being subjected such Weight 7cor stress in any direction.

Having described the invention ivliat is claimed is ii Wall construction comprising a slab having one end cut a "of; to form a horizon tal extension and a vertical shoulder the inner edge of said extension and said shoulder being provided \vithalined grooves or ridges, the inner edge of ,aid extension being fur ther provided with a trans *erse horizontal groove or ridge and the inner side of the extension being provided with a vertical groove or ridge alining with said transverse groove or ridge, and a second slab of greater height than said first slalh diposed at an e thereto and cut away to provide or r 7 ion and shoulder engage-able with shoulder and extension or said first named slab and having the inner e se of its exteir sion and its shoulder provided with alined ridges or grooves engageable with said third one fourth nained rooves or ridges respecl and havin l e inner edge of enits ridge or groove e age-able Wit l groove or r and the i BBQ L o 7 I second named slab losing provide or groove or a lele with so.
